I just found out the other day. If you have a EMS and you need the code pull for the Active diff, you will need the stock computer plug in. I went to Satain aka Mitsubishi and they could pull the code. Then went to AMS and they told me the same thing.

I've been told all you have to do is plug in the stock ecu and they can pull the code. Just an FYI. I'll be heading back to AMS to get that stupid code pulled.

If anyone has an easier way to read the code. I'm all ears.

 

There is none, same with the ABS system.
